I for one certainly appreciate the option to use MS's RBL facility
togehter with whitelisting.  My view is that using RBLs at MTA level is
too drastic - I just use my own limited blacklist of systems that are
beyond the pale.  The benefit of MS versus MTA is that the mail is
quarantined so can be released if the RBLs have got it wrong.  We
regularly find a local domain gets on some blacklist, and can then just
run a script to release all the mail from them in quarantine.

I agree with those suggesting using RBLs in SpamAssassin, but as the
current server doesn't have the horsepower to run SpamAssassin, I don't
have that option.
